About

I’m a Java Backend Developer with 3+ years of experience building scalable and maintainable backend systems using Java, Spring Boot, and microservices architecture. I specialize in designing RESTful APIs, integrating with databases like PostgreSQL, and ensuring clean, testable code using JUnit and Mockito. My experience includes working on distributed systems, implementing Spring modules like JPA and AOP, and applying SOLID principles and OOP to write production-grade code. I’ve also had exposure to Kafka, gRPC, and Agile environments, contributing to end-to-end software delivery. I’m passionate about writing efficient code that solves real-world problems, and I take pride in understanding not just how things work—but why.
